My Acer Aspire AST180 shuts down with no warning

My desktop shuts down suddenly at random times. There doesn't seem to be a trigger and it shuts off and stays off. Sometimes it won't turn back on. It seems to help to unplug the power source from the back, let it sit for a minute, and then plug it back in. You can hear it power back up after you plug it in. Any ideas?

It doesn't necessarily seem to have to do with heat.... sometimes it will shut off within 5 seconds of being turned on, sometimes it's 5 hours. And sometimes it will turn right back on, and sometimes it needs an hour.

I have the same problem, the computer just shuts down and you can hear it powering down and screen shuts off but red light on drive keeps flashing. I have the same problem, the computer just shuts down and you can hear it powering down and screen shuts off but red light on drive keeps flashing.

Sounds like you have a faulty power supply. The internal parts of your pc produce alot of heat, and if a part is heating up, then it will cause your pc to shut off.

With you saying that unplugging it , and then waiting , and then it comes back on, it sounds like once some part has cooled off, then the pc works.

My bet would be your power supply. Do make sure however, that all your parts are still tight in their sockets.. ie processor, memory , etc. I saw a pc that shut off at random times because the heat sink didn't make good contact with the processor once in college. So you want to check those things.
